Practical guidance
- Editing and saving a PDF may invalidate existing digital signatures. Use an unsigned source document; verify the downloaded PDF before relying on it.
- Encrypted or password-protected PDFs are not bypassed by the local PDF tools.
Privacy & processing
Tools described as browser-local process the working input in your browser and do not intentionally upload that tool input to AllStoic for processing. Normal hosting, security and network infrastructure may still process ordinary connection metadata needed to deliver and protect the site. Check the individual tool guidance before use.
